Orbital state vectors: Art, Position and velocity vectors & Frame of reference

In astrodynamics and celestial dynamics, the orbital state vectors (sometimes state vectors) of an orbit are Cartesian vectors of position ( r {\displaystyle \mathbf {r} } ) and velocity ( v {\displaystyle \mathbf {v} } ) that together with their time (epoch) ( t {\displaystyle t} ) uniquely determine the trajectory of the orbiting body in space.
